I'm not a CN player but I just found this vid earlier:

It says Sailor Sakura, Playboy Sasuke, Hinata Road to Ninja and Shikamaru Make-out Paradise got their models changed. Also added skillbreaks for them. If you wanna see the skillbreaks for them (in Chinese though) look here:

note: change the * in the above link to b@ng, replace @ with a.

Jib Edit: Just to note that the information for the Youtube video and the link to the Chinese Simulator are all based on the Chinese Version of the game and not the English version. So there will be some variances and differences along the way. Thanks for doing your best to reply to the question though, appreciate it! =]
